Wrapping paper

fiClaime.

This invention relates to a heat-scalable opaque waxed paper for wrapping food-stufls, and, more particularly, bread, cake, and the like.

The paper commonly used for the purpose is a sulphite or glassine sheet which as a rule has no loading, although this old wrapping sheet has in certain cases been replaced by a similar sulphitesheet having a coating of casein or the like in combination with clay, talc, and similar materials, with printing in color applied thereto on one side of the sheet, and then an outer film of parafiin wax.

I have discovered that by loading the paper, either sulphite or glassine, with titanium dioxide,

I can produce a waxed wrapping sheet which not only is of a purer white color, giving an appearance of cleanliness of particular value in wrappers of this type and at the same time increasing the brilliance of the matter printed in color thereon, but also, and what is of more importance, has an improved sealing quality-that is to say, the seal produced by the application of heat is more secure and hence is less likely to be pulled apart than that obtained with a waxed paper coated as heretofore, particularly when the coating film is thick enough to give the paper the desired degree of opacity.

What I claim as new, and desire to secure by Letters Patent, is-

1. As a new article of manufacture, a heat- Application April ll, 1932 erial No. 602,833

scalable opaque wrapping paper for food stufl's loaded with titanium dioxide and with a coating of wax applied directly to one or both sides thereof.

2. A heat-scalable opaque wrapping for food stufis comprising a sheet of paper loaded with titanium dioxide to give it the desired whiteness and opacity and with matter printed on one side thereof and a coating of wax applied directly thereto over the printed matter.

3. A heat-scalable opaque wrapping for bread and the like comprising a sheet of sulphite paper loaded with titanium dioxide and coated with wax.

4. A heat-scalable opaque wrapping for bread and the like comprising a sheet of glassine paper loaded with titanium dioxide and coated with wax.

5. A heat-scalable opaque wrapping for food stuffs comprising a sheet of sulphite paper loaded with titanium dioxide and with a coating of wax applied directly to one or both sides thereof.

6. A heat-scalable opaque wrapping for bread and the like comprising a sheet of sulphite paper loaded with titanium dioxide to give it the desired whiteness and opacity and with matter printed in color on one side thereof and a coating of wax applied directly thereto over the printed matter.
